2. List of Statistical Packages SPSS (Windows) SAS (Windows & Unix) Mathematica (Windows) Matlab (Unix) IMSL (Unix)

3. General Information IT staff will assist users –To access these packages –To find the proper procedure to analyze their data For assistance please email –assist@mcsr.olemiss.eduassist@mcsr.olemiss.edu –ccsam@olemiss.educcsam@olemiss.edu

4. SAS/willow Statistical Package This seminar covers SAS on willow –SAS/willow may be accessed from just about anywhere as long as access to the Internet is available –Access to SAS willow is free for all UM students and faculty

5. Links for SAS The main webpage –http://www.sas.com/http://www.sas.com/ For information on documentation for SAS visit –http://support.sas.com/onlinedoc/913/docMainpage.jsphttp://support.sas.com/onlinedoc/913/docMainpage.jsp SAS Resources: http://www.mcsr.olemiss.edu/mathematica/fall_sem/SASRe sources.ppt

6. Accessing SAS on willow Willow is Unix server housed in the data center building Willow’s operating system is Sun Solaris (Solaris 10) Willow is primarily used by researchers that have large number crunching programs Limited knowledge of Unix system is needed to run SAS

7. A Few Useful Unix Commands cat --- for displaying a file cd --- change directory cd 1--- to move to sub-directory 1 & so on cp --- for copying files ls --- see what files you have pwd --- find out what directory you are in rm --- remove a file pico --- a Unix editor sas --- to activate and run SAS programs To attend a Unix seminar, please contact assist@mcsr.olemiss.edu assist@mcsr.olemiss.edu

8. Accessing SAS on Willow SAS on willow may be accessed from the network. Steps to access willow from a Windows PC: –Request a willow account from the IT Helpdesk. –Download/Install SSH Secure Shell Client from http://www.mcsr.olemiss.edu/appssubpage.php?pagename=ssh2.inc http://www.mcsr.olemiss.edu/appssubpage.php?pagename=ssh2.inc –Click “Secure Shell Client”

12. Accessing SAS on Willow (Cont.)

13. Running SAS on Willow Willow is ready to execute SAS jobs –cd to the numbered directory assigned to you, e.g. cd 5 –pwd to print working directory –ls to list files in working directory –To view a program, enter: cat file-name.sas –To launch a SAS program, enter: sas file-name.sas –To view the output of a program, enter cat file-name.lst –Note that lst stands for listing

14. A Short SAS Program: test99.sas To view your input, enter cat test99.sas To run your SAS job enter sas test99.sas

15. Running SAS jobs To view your output, enter cat test99.lst

16. Example of Correlation Window/SAS corr.sas Below is an example of correlation analysis

17. The output from Correlation Below shows the output of the Correlation Analysis

18. Some SAS Proc Proc (Procedure) –proc means (obtains mean, standard deviation) –proc anova (performs simple AOV) –proc plot (plots) –proc lp (performs Linear Programming) –proc reg ( performs regression) –proc corr (performs correlation)
